I updated my HTC M8 Dual sim (HTC m8d) with the custom ROM Cdroid which is based on lineage 14 (Nougat 7.1.2)Installation with MKv2 succeded, due to S-On with recovery option install.First Bluetooth connect works incl. connection to the Premium FSE, but the phone could not disconnect and reestablish local phone network. Installed reconnect plugin and tried again,- no improvements... error messages "Get version..", "Time out.."

The solution: Put the target SIM in slot 1 of the phoneDelete all existing users in the Car System and start from scratch Configure the reconnect plugin to the second option: Restart RIL demonReconnect with fresh bluetooth coupling and allow remembering on the phoneA new car system user is created- after that calling works alreadyFor phonebook connection download the rsap phonebook app and configure IrMC only, deselect PBAPselect phonebook update in car system, select phone storage and give it a go
